Surprisingly good! I thought the characterisation, particularly of the younger group, was really strong, far better than you would expect given the title. The OAP theme, while very clever (and leading to a few very funny scenes), kind of ran out of steam, as the whole film did in the last 20 minutes, but this is well worth seeing. The acting was uniformly good, the effects impressive and the pacing really keeps up for the most part. Way, way better than I expected. Not Shaun of the Dead level, but better than pretty much everything that copied it to date....

This is really poor - not funny, not particularly gory, brings nothing original to an already crowded genre, and a bit embarrassing to see famous old faces trying to do something out of their 'comfort zone'. Trying to be Lock, Stock... meets Shaun and it isn't in the same league as either. It's like one of those cringey, humourless and sweary productions that BBC3 shows.
